The present invention relates to improvements in line casting machinesof the well known class employing a pair of vise jaws for presentinglines of character bearing matrices to a mold for i casting type bars orslugs therefrom, an example of a machine of that class being disclosedin U. S. Letters Patent No. 436,532 granted September 16, 1890 to O.Mergenthaler.

It has been proposed to provide one of the vise jaws of such machines,on the side of such jaw next to the mold, with a mark such as anaperture or cavity which, during casting, will produce a correspondingprojection on the cast slug, which will serve as a mark or guide toindi- 15 cate the point at which the slug is to be sawed ofi to thedesired length, examples of such an arrangement and of the slug producedthereby being disclosed in U. S. Letters Patents Nos. 1,434,308 and1,438,131 granted Oct. 31, 1922 and.

Dec. 5, 1922 respectively to A. H. Narrow.

It is sometimes desirable, however, especially when both vise jaws aremoved toward one another for the purpose of casting slugs without typecharacters or of centering the type characters with respect to thelength of the slugs and to avoid subsequent objections, such for exampleas objectionable printing from such projections which will stand atleast as high as the type characters on the slugs or the necessity ofremoving such projections to render the slugs suitable for use, to omitthe casting of such projections on the slugs, the omission of suchprojections from such slugs being possible since such slugs may be castto the entire length and would 35.then be suitable for use withoutrequiring any sawing off.

To enable this result to be accomplished, the present invention providesmeans whereby the aperture or mark carried by the vise jaw may berendered inoperative in any desired manner such as automatically by themovement of the vise jaws toward one another or manually.

In carrying out the invention, it is preferable to employ an aperture toserve as the mark, and

when the aperture is to be rendered inoperative automatically, it ispreferable to provide such aperture in the vise jaw and to provide apinfor closing it automatically by movement of the pin under the action ofa spring when the respective vise jaw is removed from its usual stop,

and when the aperture is to be rendered inoperative manually, it ispreferable to provide the aperture in off-center position in a circularbody which is rotatably mounted in the mold engaging face of therespective vise jaw so that the aperture may be moved out of the planeof the mold cavity by rotating such body.

In the accompanying drawing: Fig. 1 is a top plan, partly in section, ofa vise jaw provided with means for automatically closmg and opening amarking aperture therein, the jaw being shown in its normal positionagainst its stop and the aperture open;

Fig. 2 is a top plan of a portion of the vise jaw shown in Fig. 1 butshowing the marking aperture closed; I Fig. 3 is an elevation of thevise jaw shown in Figs. 1 and 2, indicating the position of. the markingaperture with respect to the mold cavity;

Fig. 4 is a top plan, showing the invention applied to the vise of atypographical machine;

Fig. 5 is an elevation of a portion of a vise jaw provided with manualmeans for rendering the marking aperture operative or inoperative; andI5 Fig. 6 is a top plan of the vise structure shown in Fig. 5.

According to the embodiment of the invention shown in Figs. 1 to 4inclusive, the rear or casting face of the Visa jaw a which ispreferably the left hand or adjustable jaw in the machine, has anaperture 0 therein at the height of the slug casting cavity a: of themold. A pin 71. fits slidably in said aperture and closes it when thevise jaw a is moved inwardly or toward the left from the position shownin Fig. 1. This pin it is located in a recess s in the matrix engagingface of the vise jaw a and is normally held in the retracted positionshown in Fig. 1 by a spring 1, the aperture 0 being then open so thatthe slugs will be 9o cast with a projection corresponding to theaperture c. In order to push the pin it into the aperture c, a pin it isrotatably mounted in the vise jaw a, said pin having a cam head or toe Ithereon which permits the pin it to recede in the aper- 5 ture 0, underthe action of its spring 2, into the position shown in Fig. 1 when saidcam head or toe l occupies the position shown in that figure, and whensaid cam head or toe l is in the position shown in Fig. 2, it will pushthe pin it into the 100. aperture 0 to such extent that its end lies inthe plane of the mold engaging face ofv the vise jaw, as shown in thelatter figure. The pin it has an actuating lever y fixed thereto andlinked to a two-armed lever m one end of which is forked to receive apin it on the lever a. The lever m is "pivoted at 11 on the guide oofthe vise jaw a and is under the control of a spring p the act-ionofwhich tends to move said lever into the position shown in Fig. 2. A barq is' freely movable end- 1-1 wise in the guide 0, it being held againstthe lever m by the jaw stop 1 on the machine when the vise jaw 11 isagainst its said stop, so that the pin h will then be retracted to openthe aperture 0, as shown in Fig. l, but if the vise jaw a ismovedinwardly or toward the left in Fig. 1, away from the stop 1, whichoccurs, for example, when casting slugs without type characters or slugswith the type characters centered thereon, the bar q will release thelever m so that it will assume the position shown in Fig. 2 under theaction of the spring p, and the aperture 0 will then be closed by thepin h.

Fig. 4 shows the vise of a line casting machine having the presentinvention applied thereto, the vise jaw a cooperating with a companionvise jaw a and both jaws being movable toward and from one another andadapted to receive and clamp a matrix line between them and hold thematrixline in casting position in front of a mold X having the slugcasting cavity at therein, the vise jaws having suitable means formoving them simultaneously and equidistantly toward one another tocenter matrix lines with respect to the used length of the slugs, suchfor example as racks u and 12 connected to the respective jaws andmeshing with an interposed pinion w revolubly mounted on the vise frame.With such an arrangement, it will be understood that while the vise jaw01, is in its retracted position against its stop 7, the latter,pressing against the bar q, will rock the lever 1n and cam head I intothe positions shown in Fig. 1 and thus allow the spring 1 to hold thepin it in its retracted posi tion in the aperture 0, thereby opening thelatter so that a projection will be caston the type character bearingedge of the type slug cast in the mold by metal which will enter saidaperture from the mold cavity which will then be in communication withsaid aperture, but when the vise 'jaw a moves inwardly or toward theother jaw, as when centering a matrix line as shown in Fig. 4, the bar qwill be carried away from the jaw stop r and the spring 10 will then actto overcome the action of the spring and rock the lever m and cam head Zinto the positions shown in Figs. 2 and 4, thereby moving the pin 71.into the aper ture sufficiently far to completely fill or close it, sothat no projection will then be cast on the character bearing edge oftheslug. .Return of the vise jaw a against its stop T will cause the latterto press against the bar q and said bar will act on the spring tensionedend of the lever m to rock it into the position shown in Fig. l, the camheadZ then occupying a position which will allow the spring 1' toretract the pin it and thereby open the aperture 0, as shown in thisfigure.

Figs. 5 and 6 show manually controlled means for the same purpose,according to which a circular body b is positioned rotatably in acircular .recess in the left hand vise jaw a, the face of this bodylying in the same plane with the casting or mold engaging face of thevise jaw a. The body I) is provided with an aperture 0 at a .pointremoved from its axis of rotation, and this aperture, as shown by thefull lines in Fig. 5,

is at the height of the mold cavity a: so that a Fig. -5, said aperturebeing then located below the mold cavity and hence out of communicationtherewith, so that a slug cast in the mold while the aperture 0' is sopositioned Will be without such projection, the body I) then presentinga smooth surface to the mold cavity at the casting level. The vice jaw ais preferably provided with a recess to receive a vertically movableplunger e having a handle d at its upper end, the plunger beingconnected atits lower end to said rotatable body by a pin 1 whichextends across a recess g in said body and accommodates the lower end ofthe plunger, the latter being depressed as shown by the full lines inFig. 5,to rotate the body I) in a direction tobring the aperture 0 intooperative position as shown by the full lines in this figure, and raisedinto the dotted line position to rotate the body I) in a direction tocarry said aperture into inoperative position as shown by the dottedlines in said figure.
